Challenge: Size Your Images

Link to the challenge:

The failing test message says
Your img element should have the class smaller-image.

Your code, which it this
<img src="https://cdn.freecodecamp.org/curriculum/cat-photo-app/relaxing-cat.jpg" alt="A cute orange cat lying on its back."></a>

is missing the class attribute and it’s value

Hope that helps.

On a side note, there was no need to create additional style tags. You could have but the selector in the existing style tags.
